HCRlin {SAMtool} | R Documentation |
Generic linear harvest control rule based on biomass
Description
A general function used by HCR_ramp that adjusts the output (e.g., F) by a linear ramp based on the value of the OCP relative to target and limit values.
Usage
HCRlin(OCP_val, LOCP, TOCP, relF_min = 0, relF_max = 1)
Arguments
OCP_val |
The value of the operational control point (OCP). |
LOCP |
Numeric, the limit value for the OCP in the HCR. |
TOCP |
Numeric, the target value for the OCP in the HCR. |
relF_min |
The relative maximum value (e.g. a multiple of FMSY) if |
relF_max |
The relative maximum value (e.g. a multiple of FMSY) if |
Value
Numeric adjustment factor.

#40-10 linear ramp
Brel <- seq(0, 1, length.out = 200)

main = "A 40-10 harvest control rule", type = 'l', col = 'blue')
abline(v = c(0.1,0.4), col = 'red', lty = 2)
